Zaffiri Precision G19 Gen 1-5 Threaded Barrel
The Zaffiri Precision G19 Gen 1-5 Threaded Barrel is the ultimate drop-in upgrade for Glock® 19 owners seeking improved accuracy, performance, and suppressor compatibility. Precision-engineered from premium materials, this match-grade barrel is compatible with Gen 1 through Gen 5 models, offering broad flexibility for both OEM and custom builds.
Each barrel is meticulously machined from 416R stainless steel—a material specifically formulated for barrel-making—then stress-relieved and heat-treated to a Rockwell hardness of RC 41. The result is a highly durable and thermally stable platform designed to withstand long shooting sessions while maintaining consistent accuracy.
This threaded barrel features a 1/2×28 muzzle thread, making it ideal for suppressor or compensator use. A matching thread protector is included to ensure safe handling when a muzzle device is not installed. Zaffiri Precision finishes every barrel with a polished chamber and feed ramp to optimize reliability with lead, plated, or jacketed bullets.
Available in three finish options to suit your style and performance preferences:
- Black Nitride: Sleek and durable with enhanced corrosion resistance
- Stainless Steel: Classic matte look with clean machining lines
- Titanium Nitride (TiN) Gold: Brilliant finish with extra hardness and lubricity
